To determine the time from the number of display lines, simply multiply the number of lines by the total line
width (not the active display width). For instance, in an NTSC system with a 63.56 s (from Table 5–5) line
width, the total vertical display time for an interlace display is:
or the display rate is: 59.94 Hz.
